There are other black screen posts on here, but none of them address my specific problem (or none that I can find) my APP.LOG is posted. Please help, I can not figure this out. All I know is that microsoft.com ERROR: GL_INVALID_OPERATION description says Operation illegal in current state. I don't know how to fix it or do a workaround.

You haven't mentioned what mods you have installed. That could be important.

But absent any other information, when OpenGL fails this spectacularly, the first thing you should probably do is reinstall your GPU driver. Make sure to get it from Nvidia and not from Microsoft or Windows Update.

I have all the default mods that come with 7th heaven installed, but no matter how few or how many I have active at a time (even with the correct load order) it still happens. My GPU driver is up to date and I only download them from Nvidia via Geforce Experience.
